I prefer to use RC paper to make paper negatives. One of my favorites is
the old Oriental Seagull Panchromatic paper. It is (was) trully red
sensitive and if you are doing any outdoor pinhole work you will love what
it does for skies. The RC is quick to dry and the paper back is blank. I
actually found a pack as recent as two weeks ago at a local San Diego
camera store.
I haven't tried Kodak's newest version of Panalure but I hear they have a
high contrast version. Actually had trouble (no image) with using a red
b/w filter on the normal contrast version of Panalure.
